Abstract: A method for exercising one or more muscles of the body wherein one or more muscle(s) are contracted to move a limb through a range of motion in opposition to an oscillating resistive force. During a muscular contraction, the direction and/or the magnitude of the resistive force changes in an oscillatory fashion thereby inducing perturbations in the musculature. The oscillations in the magnitude and/or the direction of the resistive force include a plurality of cycles during a single repetition of muscular contraction. The waveform and frequency of the oscillations may vary during a repetition or remain constant. Embodiments of devices providing an oscillatory resistive force are presented. The embodiments provide means for enabling an exerciser to perform resistance-type exercises in accordance with the method. A guided spherical bearing may be used for rotating a lead pulley or a rigid arm to create lateral resistive force oscillations.

Abstract: A breast prosthesis has a flexible shell surrounding an interior compartment. An inner surface of the shell has a plurality of flexible protuberances or struts integral therewith that extend inwardly into the interior compartment. The opposing outer surface of the shell of the breast prosthesis is preferably textured to promote tissue ingrowth. A hole in the flexible shell allows the breast prosthesis to be made in an everted configuration, then everted to provide the prosthesis. In a preferred embodiment, the prosthesis does not contain a fluid filler material and is leak and rupture-proof. The breast prosthesis may be encased in a biocompatible elastomeric shell for implantation or be made from a suitable and inexpensive elastomer and worn as an explant. The prosthesis can be made in a variety of shapes for other types of soft tissue implants.
